From Design to Specs: The Canon New Sure Shot/Prima Twin/Autoboy WT28:

Today, we’re taking an in-depth look at the Canon Prima Twin, alternatively known as the New Sure Shot in America and the Autoboy WT28 in Japan. Launched in 1990, this camera stands as a testament to Canon’s innovative strides during that era. Let’s delve right in.

Design and Features

The Canon Prima Twin is a bifocal compact autofocus camera. The design is straightforward: a slider on the front retracts the lens barrier and positions the lens in its 28 mm mode. But here’s a neat touch – with a simple button press, the lens extends to its 48 mm “tele” mode. The date back comes as a standard feature, ensuring you don’t lose track of when you clicked a particular picture. Given its name “World Traveller 28”, it’s no surprise that it can set the date of 24 cities around the globe, even considering daylight savings. Additionally, the in-built alarm can serve as a reminder, especially handy if you’re on the move. The Cameras are part of Canons successful Sure Shot Series.

Film and Film Format

The camera operates with 35mm film, which was the standard choice for many during its launch era. For optimal results:

Power Source and Battery Life

The camera is powered by a 6 V 2CR5 lithium battery. These batteries are renowned for their longevity, but as with any device, frequent usage, especially with the flash, might require more regular replacements. If you’re looking to purchase one, here’s a convenient link to Amazon.

Exposure Control and Light Metering

Equipped with a triangulation system that uses a near-infrared beam, the AF system ensures sharp images. Prefocusing is enabled, allowing you to lock onto subjects with ease. The camera’s metering range adjusts according to the lens mode you choose, ensuring optimal exposure across scenarios.

Size, Weight, and Ergonomics

Weighing in at 360g (with battery) and with dimensions of 142 x 77 x 60 mm, the camera offers a solid grip. Its ergonomic design ensures that whether you’re shooting landscapes or portraits, the process is comfortable.
